Chapter 735 The Redeemer
Yang Dongsheng's gaze immediately focused, "Which department does Toray Company belong to?"

Seeing that Yang Dongsheng was interested, the person surnamed Zheng winked at his subordinates, "Bring the thing from Luo Batou to Yang Sheng!"

A suitcase and a briefcase were quickly retrieved.

Yang Dongsheng opened the briefcase first, but it was almost empty, and all valuables had been taken away!

Yang Dongsheng only found a passport and a plane ticket from Osaka to Paris with a transit in Hong Kong.

According to the passport, the Japanese name is "Nobuyoshi Hosokawa", and the photo matches the middle-aged man just now.

When I opened the suitcase, the contents inside were also turned into a mess. Fortunately, there were still a few documents in the zippered compartment that had not been taken away.

Although Yang Dongsheng doesn't understand Japanese, he still understands the Chinese and English on the above, "东... TORAY... Tansu Suwei... Shiga..."

TORAY is the English name of Toray, "Tansu Suwei" is carbon fiber, and "Shiga" is a county near Osaka.

Toray's first T1971 carbon fiber production line built in 300 was in Shiga, which is still Toray's main factory, where there is also Toray's research center, which can be said to be Toray's base camp.

After a lot of guesswork, Yang Dongsheng managed to roughly understand it.

Hosokawa Nobuyoshi is Toray's engineer in charge of carbon fiber production. He previously worked at Toray's Shiga factory and is currently assigned to Toray's Sofika factory in France.

France is home to the headquarters of Airbus and the European Space Agency, as well as Dassault Aircraft Corporation, Peugeot Motors...the consumption of carbon fiber is very large.

Although Nobuyoshi Hosokawa does not do research and cannot help them achieve technological leaps, he is the engineer responsible for production that they need most at present.

In particular, Hosokawa Nobuyoshi is still from Toray.

According to different solvents, the production process of PAN (polyacrylonitrile)-based carbon fiber can be divided into nitric acid, sodium thiocyanate aqueous solution, dimethylformamide, zinc chloride aqueous solution, dimethyl sulfoxide, etc.

The Northwest Coal Chemical Institute originally used nitric acid, but now it uses dimethyl sulfoxide. Mitsubishi and Formosa Plastics use dimethyl formamide, Teijin uses zinc chloride aqueous solution, and Toray uses dimethyl sulfoxide. ...

According to the different spinning processes, it can be divided into wet spinning and dry jet wet spinning.

Among them, Teijin and Formosa Plastics use wet spinning, while Mitsubishi and Toray use dry jet wet spinning.

The Northwest Coal Chemical Institute originally used the wet method, but now it uses dry spray and wet spinning.

It can be seen that their craftsmanship is exactly the same as that of Toray, which is also an inevitable choice.

Dimethylformamide is poisonous, and the sodium ion of sodium thiocyanate and the zinc ion of zinc chloride will affect the quality of the raw silk.

Dimethyl sulfoxide is colorless, odorless, highly polar, high boiling point, good thermal stability, and is the best choice.

In the spinning process, the raw silk liquid of wet spinning is sprayed from the spinneret and directly enters the coagulation liquid. In this way, the core is still soft after the surface layer is solidified, and the surface layer collapses in the subsequent production process, which ultimately affects Carbon fiber quality.

However, after the raw silk liquid of dry-jet wet spinning comes out of the spinneret hole, it will first pass through the air section, and the solidification speed of the surface layer and the core is closer. The rate is the same, such a precursor has fewer defects, and the final carbon fiber product has higher strength.

Using dimethyl sulfoxide as the solvent, dry jet wet spinning is the optimal combination, which is why Toray can become the dominant player in the carbon fiber industry.

The Northwest Coal Chemical Institute may not have thought so much at the beginning, they just naturally learned from the strongest.

In the previous life, it took more than five years from the Northwest Coal Chemical Research Institute to develop T300 carbon fiber to mass production. Now with the strong support of Yang Dongsheng, Dongsheng Chemical can't improve much.

If you can directly use the ready-made experience, it is expected to greatly reduce this time.

This is an opportunity that fell from the sky, and Yang Dongsheng must take this person away.

"How much does he owe?" Yang Dongsheng asked.

"Yang Sheng wants to redeem him?" Zheng's eyes rolled.

"Yes!" Yang Dongsheng didn't hide his intention at all.

The person surnamed Zheng is an old Jianghu. He may not have heard of Dongli's name at all, but his ability to observe words and demeanor is definitely first-rate.

"This seems to be against the rules!" said the surname Zheng.

"Rules are dead, people are alive! This person is useful to me, Mr. Zheng, even if he asks for an offer, I promise not to bargain!"

"This..." The one surnamed Zheng hesitated immediately.

A person like him is full of benevolence, righteousness and morality, but how can there be any bottom line?He was just considering whether to take the opportunity to sell Yang Dongsheng a favor, or to make a fortune.

Yang Dongsheng saw the eyeballs surnamed Zheng rolling, smiled and said, "Since Mr. Zheng is not easy to ask for a price, why don't I make a price and see if Mr. Zheng is satisfied!"

"Sheng Yang, please tell me!" The surname Zheng thought for a while, and said, "That's okay, just listen to your offer, and I will choose again!"

Yang Dongsheng made a quick calculation in his mind, the price was too low to impress the surname Zheng, but the price was too high... The older the Jianghu, the less courageous he was, and Yang Dongsheng was afraid of scaring the old guy so he didn't dare to take over the business.

"2000 million Hong Kong dollars..." Yang Dongsheng stared closely at Zheng's face, and saw that Zheng's face did not change at all after his quotation. Yang Dongsheng continued, "Another 3000 million Hong Kong dollars will be paid as a hush money!"

Although the expression of the person surnamed Zheng remained unchanged, Yang Dongsheng saw his pupils shrink slightly.

It's done!

"Okay!" The one surnamed Zheng slapped his hands, "Mr. Yang is refreshing enough! But I have one more condition!"

Yang Dongsheng frowned slightly, but he still stretched out his hand, "Please tell me!"

But the man surnamed Zheng laughed, "It's far away from the shore at this time, Yang Sheng is afraid to stay on the boat for a whole night, I wonder if Yang Sheng is free, let's drink tea together?"

Yang Dongsheng immediately felt relieved, "Then bother you!"

"Yang Sheng, this way please!" The subordinate surnamed Zheng said to Yang Dongsheng.

Unexpectedly, the man surnamed Zheng did not live on the top floor with the best view on his own ship, but on the bottom floor. He opened up several cabins and built a house decorated like a palace.

There was also a pretty young girl in her early twenties in the room.

The one surnamed Zheng said to the girl, "Go and get the newly bought tea cake!"

The girl took out a piece of tea cake, and Yang Dongsheng found that this piece of tea cake was the same as the one Yang Huai took last time.

Yang Dongsheng glanced at Yang Huai, who was also very curious.

The girl pried some tea leaves from the tea cakes into the tea lotus, boiled water with a small red clay stove, scalded the teacups, and washed the tea...

Only then did Yang Dongsheng discover that Kung Fu tea is the kind of tea-making method that often appears in film and television dramas.

After drinking the tea, the surname Zheng said, "Do you want to play two games, Sheng Yang? If you lose, I will count it as mine. If you win, Yang Sheng will take it away!"

Yang Dongsheng naturally refused, and he had to talk to that Japanese Hosokawa Nobuyoshi about his future.
